Vortec Swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 74 C20, and it has a good running but tired 350.

Earlier I was looking on CL looking for a Vortec 350, and saw a few "running" 5.3's or 4.8's for a good price.

I know they practically drop in, and manifold selection is good. So how is the MSD ignition kit for reliability, and drive ability? I want to keep the truck carb'd so I don't have to deal with the extra costs of the swap. Like all the electronics, and new gauges I would need to make the set-up work.

I figure this swap would have a T200R4 overdrive, and 4.11 gears which should work nice on a 5.3.

Has anyone swapped a carb'd LS motor, and how did you like it? In the end do feel its still worth or is 1/2 the LS magic in the electronics?
